How To Apply a Nail Hardener?

Make sure your hands are clean, as well as your nails. Remove any previous nail polish with acetone, as well as dirt underneath your fingernails. Use your nail hardener and apply a thin layer by making 3 strokes. One stroke should go right down the centre, and other two should ”hug” the sides. Let it dry for 10 minutes and then go in with your favourite nail polish colour.

  • However, if you have extremely week and brittle nails, you should repeat the nail hardening process for the following 7-14 days.
  • Apply a new coat every day and then remove it with acetone when you get to the seventh day.
  • Then, redo the entire process all over again.
  • Once you start noticing improvements, you can start applying the nail strengthener only once a week.

How To Get Strong Nails

In order to achieve, maintain, and enjoy your long and healthy nails, you should obey some simple rules. 


Moisturising is a must! Your skin, hair, body, as well as your nails, demand a lot of moisture. Our nails tend to become brittle and they dry out quickly during winter; therefore you need to moisturise them especially during this period. You can achieve this by using a bunch of different oils that are loaded with vitamin E, and this way you will prevent them from drying out. This means no more sudden peeling or breaking.


Be very delicate when you trim your nails. Cutting them is a lot like trimming the ends of your natural hair- if you don’t do it often enough, it will split on its own. Use a good pair of nail clippers, and trim your nails at least every two-three weeks. This way you will also stimulate the growth, and only maintain the healthy part.

Avoid Water

Try not to soak your nails with water of any kind since water can soften your nails. Sensitive, brittle, or dry nails, can look week, and the nail beds can expand once they absorb all the water. You should wear rubber gloves when washing the dishes since this way no water can come in contact with your nails. Also, you should avoid spending a lot of time at the pool, steamy saunas, or hot showers since these can weaken your nails and the nail bed.

Learn To File

Avoiding those poorly made metal files is a must since they can act too rough on your natural nails. Use a grit cushion or any nail file that has soft edges. Make sure your moves are slow and steady and don’t make too sudden movements. Always file in one direction since filing back and forth can cause your nails to tear or rip.

Nail Supplements

Biotin is the most used supplement when it comes to nail boosting and growing. Some researches believe that even up to 25% of women can improve their nail thickness in time by using supplements. However, it takes at least 3 months for you to notice the difference, although you should talk this through with your doctor before proceeding further. If you do end up purchasing any of these supplements, make sure you give them enough time to work and for you to spot the difference.

Avoid Chemicals

Chemicals are actually acetones, acrylics, nail polishes, gel polishes and other items that contain relatively harsh ingredients. Any of these ingredients can cause your nails to dry out and to appear thin. You should use non toxic nail polishes or some that are cruelty-free since they won’t strip off your natural oils. Also, always read those labels at the back, and only purchase polishes that contain natural ingredients.

Take Care of Your Cuticles

Some nail specialists recommend removing and cutting cuticles around your nails, while others advise avoiding it. Scientifically speaking, if you want to prevent possible breakage or damage, you should leave your cuticles as they are. They actually serve you as a protective barrier, and without them you might be exposed to some infections or ridges. The best advice is for you to push back your cuticles with the help of a wooden stick and let them stay as they are. Don’t trim them down with clippers, and always moisturise after being done with cutting.

Healthy Lifestyle

A healthy diet is the best option for your nails, hair, body, lashes, skin: basically anything and everything. Women who watch out for their health and who eat correctly will probably have the best looking nails. Any food that is rich in antioxidants will leave you with smooth and long nails. Also, anything that contains a lot of magnesium or calcium, as well as vitamin D, is an excellent idea for you to add to your everyday routine.

Go With Shorter Nails

Although many of us love long and sharp nails, sometimes shorter nails are the way to go. Avoid growing them out to extreme lengths since you can break them a lot easier. Another great plus when it comes to shorter nails is that they are low maintenance and that they won’t take too much of your time when you paint or cut them.
